The mobile network carrier`s signal in Galaxy Grand changes from time to time whatever or whichever signal is readily available for your device to pick up. If there are no 3G signal around for your device to pickup, it switches to a 2G mode. So you should be in an area with a strong 3G signal so that your device will maintain to be in that 3G mode.

Welcome to Ask Me Fast!

Hi there!

Samsung galaxy grand duos can be configure in the the "mobile networks" settings in the Android configuration menu. This phone has two tabs in the menu which lets the user configure all these values for each SIM card independently.

Selecting which SIM card is used for the 2G/3G chain and which one for the 2G-only chain is hidden behind the "Use only 2G network option".

If activated for one SIM card the option is automatically deactivated in the options on the second tab for the other SIM card. In other words, it is not possible to set both transceiver chains to 2G-only mode.

If the network operator of the SIM card configured for the 2G/3G chain does not have a 3G network, both transceiver chains use a 2G network and it can be different ones.

Once both chains have connected to a network, two independent signal strength indicators are shown in the Android status bar at the top of the screen.

In the status pull down menu, the network name of each network is shown (`Telekom.de` and `O2 - de` in the first picture above) and the user can select from which SIM card to originate phone calls and SMS messages.

FOR NETWORK SELECTION:

While each SIM card per default searches for the home network or a roaming network automatically, it is possible to perform a manual network search on a per SIM basis and select a different network when roaming.

Before using the data service for the first time it is necessary to configure whether SIM1 or SIM2 should be used for data. If the data service is used on a SIM card that is configured for the 2G-only transceiver chain, only GPRS or EDGE is available.

If configured for the other SIM card, the 3G network is used if available. This can be changed at runtime and no reboot is required. The picture on the left shows how this is configured in the `SIM card manager` option in the Android Settings.

For example, In the example, data service is currently configured for SIM1, while outgoing voice and SMS messages are configured for SIM2 as can be seen by the blue `2` logo in the status bar.

Hope i was able to explain it clearly..and answered your query. Please let me now if you have anymore questions regarding this issue.

Please call your network carrier so they can check it the settings for the mobile network is correct. What you can do as well is try to manually search for network and select the appropriate network for your SIM cards. On how to do it go to Settings and then Mobile Networks. Under Mobile Networks select search for Network Operators and then Manual Search. If this does not work again best is call your network carrier for assistance.

In the Samsung galaxy series of phones, network mode can be seen at the SETTINGS > MORE... > MOBILE NETWORKS > NETWORK MODE. 3G is automatic activated in the phone when you used the Packet data as your internet connection. When you get connected in your Packet data connection, the 3G signal will automatic appear in your screen when the signal is strong in your location. If the signal appears as E or G, then the signal in your town is too poor so the 3G is not show.

I`ve read that you cannot change the default storage location on your mobile phone Samsung Grand. All mobile phone or tablets which have a higher internal memory cannot use sd card as the default storage.

But you can change the camera image and videos storage location to your sd card
1 Run camera app
2 tap gear icon or the settings
3 look for storage then tap it
4 select sd card.

Try to see if you have a access point name in your phone:

1. go to settings
2. wireless and networks
3. mobile network
4. look for access point name and see if it contains something
5. if it has access point name, choose one. If it don`t have, try to contact your network service provider and ask for the configuration for your phone.
